WALTER R. SCOTT, OE IPHILADELEPHIA, PENNSYLVANIA, ASSIGNOB TO JOSEPH H.BROMLEY, OF PHILADEIEHIA, PENNSYLVANIA.

JAG QUARD CONNECTION.

Application filed May 31, 1910.

To (ZZZ whom it may concern ie it known that I, WALTER R. SCOTT, citizenof the United States, residing in the city of Philadelphia, State ofPennsylvania, have invented certain new and useful improvements inJacquard Connections, of which the following is a full, clear, and er;act description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to machines employing a plurality of sections ofthread-controlling jacks 0r heddles actuated by one or more jacquardmachines, and consists of connecting actuating devices between saidelements. In substance it comprises the substitution for thecompensating element of the jacquard connection shown and described inmy prior U. S. Patent No. 921,288 dated May 11, 1909, of animproved formand character of the compensating element, and also a carrying forwardof the invention disclosed in that patent, whereby the plurality ofsections may be actuated, by such jacquard connections, in sets; that isto say one jack of one section in unison with a corresponding ack ofanother or other ections in the series of sections.

In the accompanying drawings illustrating my present invention; Figure 1is a side elevation of a plurality of my new compensating elementsconnected in series which in turn connect the several jacks in a sectionor series of jacks to each other and to a jacquard machine. Fig. 2 is alike view of part thereof illustrating an arrangement thereof wherebythe corresponding jacks in a series of sections may be operated in sets;and Fig. 3 is an end elevation thereof showing the method of mountingthe compensating devices on their shafts.

As stated in my previous patent mentioned, the primary object of theinvention therein described and in this is to substitute for the seriesof textile strings, of great and unequal lengths between the jacquardhooks and the jacks controlled thereby, of means largely, if not wholly,metallic, of compactform, due to their intrinsic character, and adaptedto communicate the action of the jacquard to the several jacks in equaldegree and with certainty of action, whereby uniformity in the productfabric made by the machine, may be had as an ultimate result, aside fromthe assured per- Specification of Letters Patent.

fect working of the acks, under all conditions.

The invention is applicable as well for use with Jacquard looms forweaving a plurality t' fabrics, or to any machine in which it is desiredto move a plurality of movable elements in unison through a jacquardconnection, and particularly develops its greatest utility in connectionwith lace curtain machines in which there are a series of sections ofjacks operating to produce a corresponding plurality of the samepat-tern, in the curtain, each jack being mounted independently on arocking bar, and actuated or controlled by a directly operativeconnection with the jacquard machine, the jacks being operated in setscomposed of corresponding jacks in each of the several sections, and inunison through appropriate lifting hooks of the jacquard.

1n the operation of the device of my former patent I found that while itoperated perfectly to perform the functions stated and desired, theparticular form and mode of operation of the compensating element shownwas such that the wires connecting each two contiguous compensatingmembers in a series necessarily crossed each other and producedobjectionable friction and wear. My present form of compensating elementand its mode of operation are such that the connecting actuating wiresbetween contiguous compensating members are reduced one-half in numberand are all in the same horizontal plane; the lifting action of each onthe particular jack with which it was connected made more direct andcertain; and finally that the useful application of the new compensatingmember could be extended by applying it, in inverted position, and by apair of suitable connecting wires one horizontal and the other vertical,between the last in sequence of compensating members in a set and thelifting hooks of the jacquard, to operate a connected set of jacks as anentirety, through the one direct connection with the jacquard, and alsoto accomplish the greatlydesired end of locating the jacquard entirelyto one side of the series of jacks so actuated and hence in a decidedlylower plane than formerly.

Referring now to said drawings illustrating an application of theinvention to a lace curtain machine, the compensating member isconstructed in the form of a bell crank lever, indicated in a series ofthem as at .100, in Fig. 1, and mounted rotatably on shafts indicated at82, with one arm 103 of the lever extending horizontally, and its otherarm 10 1 extending vertically. Each lever is provided with alaterally-extending hub 109, shown in Fig. 3, in order that a number ofthem may be mounted in spaced relation on the same shaft 82. The leversin a set are connected, one to the other, by a wire 105 drawn throughperforations (3, (3 in the upright arm 10a, and each is connected to ajack, through the medium of its lifting cord 64. and intermediateadjusting. device 98, by a depending wire 66 drawn through a perforation9 in the horizontally extending arm 103 of the lever. It will thus beseen that, while each lever directly and independently actuates theparticular jack with which it is thus alone directly connected, theseries of levers in the set are so connected that a sidewise pull on thevertically-disposed arm 10% of the last lever in the series will rockall of them on shaft 82, and which action will, in turn, lift all of thejacks, in such set, in unison. In order to give such sidewise pull tothe terminal lever, there is connected to its upright arm 10% a wire 106similar to and arranged in the same plane with the set ofjack-connecting wires 105, the opposite end of this wire 106 beingconnected to the arm 107 of another bell-crank lever, indicated at 10%,mounted rotatably on a shaft 84, and precisely similar in constructionto the other levers 100, but arranged thereon in relatively invertedposition, so that when rocked on its shaft its arm 107 will have asidewise instead. of a vertical movement and its arm 108 a verticalinstead of a sidewise motion. Drawn through perforation 8 in said arm108 of lever 10 i is a wire 77 leading, through similar adjustingdevices 80 as before, tothe lifting hooks of a jacquard machine.

My present form of compensating devices enables me to arrange andoperate the j rick-actuating connections, and their shafts, in staggeredrelation, as indicated in Fig. 2, which has advantages when operatingcorresponding jacks in the several sections, in sets, and so actuatingthem by means of corresponding lifting hooks of one or more jacquardmachines. By reference to Fig. 3 it will be seen that this form andcharacter of compensating device, operatively connecting a plurality ofjacks in series, and as employed, in reverse position to connect theseries as a whole with the jacquard machine, lessens the number ofcompensating devices and all crossing wires, and, as com pared with myformer device of said Patent No. 921,288, also enables me to arrange thejacquard machine in a vertical plane entirely to one side of that of thewhole series of jacks operated thereby and also in a horizontal planevery much lower than when employing the form of compensating device ofmy said former Patent No.

921,288; and also finally to utilize my present form of compensatingdevice in such described relative arrangement with the jacquardmachine,'which is also shown and described in a pending application forpat ent filed by me on March 17, 1910 Serial No. 5%),907, and insubstitution for the roller devices shown therein, between thejackactuating connections; but as I have, in said application, claimedsaid arrangement of elements, broadly, I do not claim the same hereinsave as a specific form thereof, comprising as an identifying elementthe particular connecting and compensating element herein shown anddescribed and in the specific combination thereof with the wireconnections between the series of jacks and the jacquardmachineactuating the same.

Having thus described my invention, I claim as new and desire'to secureby Letters Patent 1. In a machine of the character recited,

a plurality of independently movable acks, 7

constituting a section thereof, a shaft, a series of inverted bell cranklevers each having a bored laterally extending hub and mounted therebyin spaced relation to rock on. said shaft, vertically disposed liftingmeans between each jack and the horizontally-disposed arm of each lever,and. means connecting the appropriate lifting hooks of a jacquardmachine with the other and vertically-disposed arm of each correspondinglever inthe series.

2. In a machine of the character recite-d, a plurality of independentlymovable jacks, constituting a set of jacks, a series of shafts over eachjack in the set, an inverted bell crank lever on each shaft, providedwith a bored hub adapted to be mounted thereby to rock on said shaft,vertically disposed lifting means between each jack and thehorizontally-disposed arm of its corresponding lever, means between theupright arm of each contiguous lever in the series, connecting the setof levers, in tandem, movable actuating and guiding means operating toimpart a sidewise motion to the upright arm 7 of the last lever in theseries, and means between the lifting hooks of a jacquard machine andsaid movable guiding means, operating to simultaneously rock the entireseries of levers in the set. i

3. In a machine of the character recited, a plurality of sections ofindependently movable jacks, arranged to be operated in sets ofcorresponding jacks in the several sections, a series of shafts mountedin relatively different horizontal planes, one shaft for each section ofjacks, a series of inverted bell crank levers mounted on each shaft, inspaced relation to each other, and adapted to rock on said shaft,vertically disposed lifting means between each jack in a section andhorizontally--disposed arm of a corresponding lever on its shaft, meansconnecting the upright arm of contiguous levers in a set, in tandem, toa set of corresponding jacks in the several sections, and a series ofmovable guiding levers connecting the appropriate lifting hooks of ajacquard machine with the terminal member in the series of leversactuating each set of connected Jacks.
